I bought these from American Muscle.
Smoked Mustang Headlights (99-04) at AmericanMuscle.com - Free Shipping!
Got the $40 Sylvania Silverstar bulbs to go with them but to be honest they still aren't very bright through the dark tinted lenses. Everywhere I drive though is well lit so it has never been a concern.
Gave the front of my car a whole new mean look. I love them.

I would buy those from AM before going through eBay. You know exactly what you're getting by reading reviews, looking at the customer-uploaded photos, and the ones I just showed you, not to mention they're very reputable and have great customer service. The lenses are alot darker than most of the pics portray them to be. I think mine are a pretty accurate representation of how dark they are.
And for the record, I bought the silicone to seal mine but it looked like a pain in the ass due to some tight spots so I just said screw it. If they get condensation I'll dry them in the sun as mentioned in the tutorial, then seal them. They have small drain hoses in the back to let moisture out. So far I have had zero issues. They look GREAT.
They go good with the taillights from AM also.

These are the dark smoked headlights. Not sure how much darker they can really get haha I was told the ones I bought were lighter than the Dark Smoked, but looking at RasikaJay's car they appear much darker than the "Dark Smoked." Also, whether it matters to you or not, mine have the amber corners which I really started to like, but the Dark Smoked have cleaner silver/smoked corners I believe. Both look really good in person.

And here are the taillights.

I loved the taillights the minute I put them on too. AM actually used my car in a couple of their ads.
